The MR73 was developed for use by French police and Special Weapons and Tactics units, including the legendary GIGN, who needed a reliable sidearm for use in the field and could stand up to their incredibly punishing training regiments that involve firing 150 rounds at daily target practice. Every aspect of the MR73 has been optimized for high performance, it features a unique trigger system that delivers one of the smoothest trigger pulls ever found on a double action with zero-creep. The cylinder of the MR73 is fully machined from forged, ordnance-certified steel billets, and the chamber finish is conducted by an impact process resulting in remarkably smooth chamber walls and long service life. Before being released, each revolver is test-fired for accuracy at the factory, where it must be able to achieve a grouping diameter of 20mm at a range of 25 meters, any MR73 unable to achieve this level of accuracy is not released. - CALIBER .357 MAG/.38 SPL - CYLINER 6rd Billet Steel - BARREL 4" - SIGHTS Front Black Ramp, Rear Adjustable white dot w/narrow window for bullseye shooting - TRIGGER Factory Modified w/zero creep - GRIPS Trausch Rubber Beavertail Style
